NCalc.dll has failed the NXCheck check

I got the following warning when running my application through the Windows Certification program:

WARNING 3
Binary analyzer
Warning: The binary analyzer test detected the following errors:
File C:\Program Files (x86)\Streets Heaver\Compucare8\NCalc.dll has failed the NXCheck check.
Impact if not fixed: If the app doesn’t use the available Windows protections, it can increase the vulnerability of the customer's computer to malware.
How to fix: Apply the SAFESEH, DYNAMICBASE, and NXCOMPAT options when you link the app. See link below for more information:
